This sorta what happened with me and Tidbit
I brought her home and contacted all the vets, pounds, animal shelters in the area but after a few weeks no one was looking for her I kept her.
I also put up posters with just
8 weekish old kitten
street name that i found it on
Please contact me at phone number
I took her to the vets which looked her over confirmed her age, dewormed her and gave her her first road of shots.
We also had to rush and pick a name so they could file her!
